Clipse doesn't like the husky that lives two doors down from us. I'm not sure why. Before their yard was done they used to tie it up in the front, and when I was walking the dogs past Clipse would get all antsy and posture as we went by. He has met the dog before and they haven't had a problem he just doesn't like him from afar I guess. LOL

My co-worker's dog has a thing against boxers. He's never had a bad experience with them he just hates them. She has to be careful while walking him at the offleash. If she sees another boxer she calls him over to her and makes him heel. When another of my co-worker's got a boxer puppy we were a little concerned as to how Sydney would react, but since Jackson was just a pup when they were introduced it's like Sydney doesn't realize he is a boxer. To Syd he is just Jackson his friend.

My boss's old bouvier also didn't like husky or husky type dogs. When those dogs came in for grooming we would have to put Virgil (the bouvier) away.

Also I've noticed that a lot of dogs don't like pugs. My grandpa's pug is really friendly and outgoing, yet he gets a lot of growls from dogs or dogs will run to get away from him. I think it may have something to do with how they look and how they sound that other dogs aren't used to.
